I run a 160deg T-stat and engine temps rarely rise above 170s.
One day on a local cruise of the twisties in 2nd gear, we took a brief pause and I noticed that temps were approaching the 200deg mark.

It won't matter since the tstat would be open anyway unless it was a 180.

A lower temp thermostat makes the car run cooler on the street because it opens sooner and never really has a chance to get warmer. On track the water temp will reach the same equilibrium in a 20min session with a 180 stat as it would a 200, 212, or 220.

When my car was stock I constantly saw 230+ water temps and 280+ oil temps within a handful of laps. I would have to do cooldown laps within a 20-30min session to keep from overheating. Now my car is a dedicated track car with an aluminum radiator and separate oil cooler. I can run the car all day and water is around 210F and oil hovers around 230-250F without a fan. I have a single small 14" spal fan I only use when I am in line to go out or coming in off track. On track the air moving through the radiator is faster than the fan can pull anyway.
